Rabbit meniscus repair for 6 weeks culture. A wound was made on rabbit meniscus with a diameter of 1 mm, filled with rabbit bone marrow stem cells (BMSCs; a, d, g, j) or rabbit meniscus stem cells (MMSCs; b, e, h, k) and cultured with 10 % FBS-DMEM for 6 weeks. The meniscus was cut into 10 μm section and stained by toluidine blue (a, b), safranin O (d, e), fast green and safranin O (g, h), alcian blue (j, k). More than 90 % of the wound area in rabbit meniscus was healed by MMSCs treatment, in contrast with BMSCs treatment only 80 % was healed (c, f, i, l). The wound filled with MMSCs was healed much faster than that filled with BMSCs (*P < 0.05)
